| 摘要 |
<p>The invention relates to a heating/air conditioning unit (IC) comprising: (i) a compressor (CP) for heating and pressurising a cooling fluid; (ii) an internal condenser (CDI) which, in the heating mode, assists in heating the inside air by means of exchange with the cooling fluid originating from the compressor (CP) and which is dimensioned to substantially integrally condense the cooling fluid, originating from the compressor (CP), in the heating mode, such that it is substantially entirely in a liquid phase; (iii) an external pressure reducing valve (DTE) which, in the heating mode, depressurises the cooling fluid; (iv) an external evaporator (EE) which, in the heating mode, heats the cooling fluid originating from the external pressure reducing valve (DTE) by means of exchange with the outside air in order to supply the compressor (CP); (v) an internal evaporator (EI) which, in the cooling mode, cools the inside air by means of exchange with the cooling fluid; and (vi) a subcooler (SR) arranged so as to subcool either (i) the cooling fluid originating from the internal condenser (CDI) in the heating mode in order to supply the external pressure reducing valve (DTE) so that the external exchanger (EE) can be heated or (ii) the cooling fluid originating from the external exchanger (EE) in the cooling mode so that the cooling capacity of the internal evaporator (EI) can be increased.</p> |
